Quad, 14-Bit nanoDACs® With 5 Ppm/°C On-Chip Reference, I2C® Interface

The AD5625R AD5645R AD5665R and AD5625 AD5665 members of the nanoDAC family are low power, quad, 12-/ 14-/16-bit, buffered voltage-out DACs with/without an on-chip reference. All devices operate from a single 2.7 V to 5.5 V supply, are guaranteed monotonic by design, and have an I2Ccompatible serial Interface
The AD5625R AD5645R AD5665R have an on-chip reference. The AD56x5RBCPZ (LFCSP) have a 1.25 V, 5 ppm/C reference, giving a full-scale output range of 2.5 V; the AD56x5RBRUZ (TSSOP) have a 2.5 V, 5 ppm/C reference giving a full-scale output range of 5 V. The on-chip reference is off at power-up, allowing the use of an external reference. The internal reference is enabled via a software write. The AD5665 AD5625 require an external reference voltage to set the output range of the DAC
The part incorporates a power-on reset circuit that ensures the DAC output powers up to 0 V (POR = GND) or midscale (POR = VDD) and remains there until a valid write occurs. The on-chip precision output Amplifier enables Rail-to-Rail output swing.
The AD56x5R/AD56x5 use a 2-wire I2C-compatible serial Interface that operates in standard (100 kHz), fast (400 kHz), and high speed (3.4 MHz) modes.
